Not every driver knows what tire pressure should be, even if sometimes he watches it. Most people assume that when changing seasonal wheels at a tire shop, they will set the pressure that will last the entire season. And almost no one knows that tire pressure needs to be adjusted depending on the situation. This article aims to fill in the gaps on such an important issue. Today we will talk about what should be the pressure in the tires of VAZ, KIA and passenger-and-freight GAZelles.

How important is the correct pressure inside car tires?

Of course, when choosing tires, the driver looks at the manufacturer, reviews of a particular model and the price tag. For safety on the road, the tire must be of high quality and from a trusted manufacturer. But even the most expensive tirescreated with the latest technology, will not fully work out their functions if they are set to the wrong pressure. This, in turn, affects factors such as:

• car handling;
• safe maneuvering on the road;
• even tire wear;
• appearance of a "hernia" on the cord;
• increased fuel consumption.

For example, if the wheel is overinflated, then when hitting a curb or other obstacle, the tire may explode. If the pressure is set incorrectly, the car will turn worse in corners.

How often should I check tire pressure?

Experienced motorists always carry a pressure gauge with them - a device for determining tire pressure. If available, it is recommended to use it once every two weeks and before every long trip.

If you don’t have a pressure gauge or you don’t know how to use it correctly, then go to a tire shop at least once a month to determine the pressure in the wheels. The verification service is very inexpensive and takes a minimum of time.

Not only seasoned drivers can tell if a tire is flat. Therefore, every time before starting the car, conduct a visual inspection of the tire. If you have low-profile tires, then it will not be possible to determine the presence of a descent by eye.

How to use the pressure gauge?

About what pressure should be in the tires, we will tell below.

Now, since the topic has begun to be developed, let's see how to measure blood pressure correctly.tire, having a pressure gauge. Instructions for use are on the back of the package, so do not rush to throw it away. But even in its absence, problems should not arise, just unscrew the valve cap on the tire, put on the pressure gauge tube, wait until the reading stops at one mark (pressure gauge needle, electronic numbers).

It would seem that there is nothing complicated, but there are a number of factors that affect the correctness of the testimony. Tire pressure is measured under the following conditions.

1. Only on cold tires! If measured on a hot one, then the reading error will be from 10 to 20%. The driver, of course, wants to lower the tire, but this cannot be done, since the pressure will become deliberately low. Remember physics, friends: when heated, the body expands, and when cooled, it narrows. This also applies to air, in a hot tire the molecules are expanded, and the pressure indicator will be too high. Take measurements 4-6 hours after your trip.
2. If there is a need to check the pressure during the journey, that is, on a hot wheel, then use the advice: if the pressure goes off scale by more than 20%, lower the wheel by 5%. If the pressure is less than the norm of a cold wheel by 10%, then pump it up by 10%. After the tires have cooled down, measure again.
3. It is necessary to measure the pressure on all wheels, as it can be different.

Use the pressure gauge as often as possible in winter, as readings can drop from 0.3 to 0.5 atmospheres.

How do I find out the recommended pressure?

Many motorists are armed with an automatic compressor in order to be able to inflate tires at any time without resorting to the services of a tire fitting specialist. In modern compressors, a special pump is installed that will not allow the wheel to be pumped, the operation of the device will stop when the pressure returns to normal. But the compressor can't tell you when to loosen it up a bit.

Also, you can not rely only on the operation of the compressor, because he cannot know what pressure should be in the tires of a particular brand of car. There are other factors that affect the correct inflation: the weight of each car is different, as well as its technical characteristics.

About what pressure should be in the tires, it is written in the service passport for the car. Also, these parameters are indicated on the stand located next to the driver, or on a sticker near the gas tank.

Recommended pressure on the tire itself: is it worth relying on?

A manufacturer of car tires indicates various parameters on the side of its side: size, speed limits, maximum weight, as well as pressure recommendations.

But don't follow the given parameters. Pressure should be determined by the following factors:

• wheel radius;
• weighing the car itself;
• season: winter or summer;
• road surface;
• load on the wheel (for example, for r14, the average reading should be2, 2 atmospheres, and at full load of the car all 2, 4).

In addition, the pressure is often set differently for the wheels of the front and rear axles (this applies mainly to VAZ cars). And it is determined by the type of leaders.

Experienced motorists recommend keeping the pressure at the minimum level recommended by the factory during standard use of the car, since the grip of the sole of the wheel with the road will be the best, which means that driving will become as safe and comfortable as possible.

We propose to consider the question of what pressure should be in the tires of the VAZ.

VAZ tire pressure

Introducing a list of recommended tire pressures for VAZ vehicles. We no longer began to look for parameters for models such as Kopeyka. Let's start the review with 2104.

1. VAZ 2104 with wheel sizes 175/70 R13: pressure in the front - 1.6 atmospheres, in the rear - 2.2.
2. VAZ 2105, 2106, 2107 with standard size 175/70 R13: front - 1.7 atmospheres, rear - 2.0.
3. VAZ 0108, 2109/99, 2114/15, 1118 Kalina with sizes 175/70 R13: front - 1, 9, rear - 1, 9.
4. VAZ 2110/11/12 - here you can install wheels R14 175/65 and R14 185/60, but the pressure on all four wheels should be 2.0 minimum.

We talked about what should be the tire pressure in VAZ passenger cars at minimum rates. It is necessary to be guided by the load of the car. If you have loaded it to the maximum, thenpressure must be increased from 0.1 to 0.4 atmospheres!

And what should be the tire pressure in winter? Nothing changes here, maintain the recommended indicators. Check the parameters steadily with a pressure gauge, as under the influence of cold the air narrows, thereby lowering the pressure in the tires.

Gazelle: what should be the tire pressure

The most common truck on Russian roads is a GAZ car, or, as we are used to, a GAZelle. This is a real "workhorse" that is ready to work seven days a week, with overloads and other difficult operating conditions.

What pressure should be in the tires of this wonderful car? The following indicators are recommended by the factory.

1. GAZ 7505, 3302, 33023: standard wheel size 185/75 R16. It is recommended to keep the pressure on both the front and rear wheels at 3.0 atmospheres.
2. GAZ 3221: wheel size 185/75 R16. It is recommended by the factory to maintain minimum values on the front wheels of 3.0 atmospheres, and on the rear wheels - 2.8.

Tire pressure recommendations for GAZelle drivers

It's one thing to follow the recommendations of the GAZelle car manufacturer, another thing is to heed the advice of experienced drivers of this truck, who have gone through fire and water on this "horse". And here's what they suggest.

If the car is not loaded, it is enough to maintain a pressure of 2.8–3.0 atmospheres. If you need to transport cargo (partial or full load), it is recommended to pumpwheels from 2.2 to 3.4 atmospheres so that the contact patch between the tire and the road surface is optimal.

To take the advice of drivers or be guided by the instructions of the factory is a purely personal matter.

KIA tire pressure

KIA is one of the most popular car brands of the middle price segment on Russian roads. A variety of models, good factory specifications, excellent customer reviews and build quality - all this affects the choice when buying such a car.

Consider the question of what pressure should be in the KIA tires.

1. For the Rio model from 2000 to 2011, regardless of the size of the tire, the factory recommends maintaining a minimum pressure on all four wheels - 2.1 atmospheres.
2. KIA "Rio" from 2011 release - 2, 2 atmospheres, despite the size of the tire.
3. KIA Picanto from 2004 to 2011 - 2.1 atmospheres for any wheel size.
4. KIA Picanto since 2011 - 2, 3 atmospheres.
5. KIA Venga of any year of manufacture and regardless of tire size - 2.2 atmospheres.
6. KIA Soul of any year and with any tire size - 2, 3 atmospheres.
7. KIA Mentor-2 of any year and with any tire size - 1.8 atmospheres.
8. All KIA Cerato with any tire size - 2.1 atmospheres.
9. KIA "Sid" - any year of production and all wheel sizes - 2, 2 atmospheres.
10. KIA "Optima" - 2, 3 atmospheres.
11. KIA "Sportazh" until 2005 release - 1.8 atmospheres.
12. KIA "Sportazh" from 2005 to 2010 - 2, 1 atmospheres.
13. KIA Sportage since 2010 – 2, 3.

We will not write in detail about what pressure should be in winter tires of KIA cars, because the values are equal for each season. Just check the indicators more often, using a pressure gauge or visiting a car service.

Do I need to spend money on pumping nitrogen into tires?

Today, car service centers offer to pump pure nitrogen into the wheels instead of ordinary air. This supposedly affects tire pressure. Experts explain that tires inflated with nitrogen are less responsive to temperature changes, and thus the driver will not need to check the pressure and inflate the wheels so often.

But, as practice has shown, this is a waste of money! Tires filled with nitrogen, like regular air, weaken when cold and expand when heated.

When can I lower the wheels?

Surely many drivers have heard from experienced riders that sometimes it is useful to slightly lower the pressure in the tires. And what is it for? Should tires be deflated to the lower limit of the recommended parameters?

1. Some people deflate tires in the winter, explaining that this improves the grip of the wheel with the road. But experts do not advise doing this, since at low temperatures the indicators themselves become below normal. Maintain the recommended pressure in the winter, because at the moment when the car starts moving, the rubber will warm up, and with low inflation, as it was alreadyit is written, wear will begin much earlier. A warm tire has optimal traction, so there is no need to deflate.
2. By lowering the wheels for off-road driving, the driver makes the car easier to cross, as the tire starts to work like a tractor caterpillar. But this again affects wheel wear.

An inexperienced motorist does not know to what extent it is possible to reduce the pressure in the tires of a car. What it should be according to the recommendations, keep it that way: experiments rarely lead to good results!
